hospital management app + low cost AWS is very realistic
Let’s design this simple, safe, and cheapest possible architecture, especially suitable for Indian hospitals / clinics.
You already have:
✅ Frontend
✅ Backend (Node/Express)
✅ MongoDB
Now we’ll host it with minimum monthly AWS bill while still being reliable.

₹900–1000/month
This is the cheapest safe setup on AWS.
✅ Why this is best for hospital app
✔ Patient records safe
✔ No complexity
✔ Easy maintenance
✔ Very low cost
✔ Can scale later
✔ Works 24×7
Hospitals usually don’t need auto-scaling initially.
隣 Recommended Setup (Step-by-step)
1️⃣ EC2 Instance
Choose:
t3a.micro (best price/performance)
Amazon Linux 2023
20 GB disk
This is enough for:
50–100 daily users
OPD, billing, reports, staff login
2️⃣ MongoDB — DO NOT host yourself
❌ MongoDB inside EC2 (risk + data loss)
✅ MongoDB Atlas
Use:
M0 free tier (512MB)
Or M2 (~₹800 if data grows)
Benefits:
Auto backup
Secure
No admin work
Very important for hospitals.
3️⃣ App Deployment (Two options)
OPTION A — Simplest (Recommended)
Without Docker
Backend → Node.js + PM2
Frontend → React build served by Nginx
Copy code
/var/www/frontend
/var/www/backend
Advantages:
Very cheap
Very easy
Less RAM usage
Best for hospitals.
OPTION B — Docker (slightly heavy)
Only if you already know Docker well.
Still fine but needs more RAM.
4️⃣ Nginx (Important)
Use Nginx for:
Frontend hosting
Reverse proxy
SSL
Example:
Copy code
hospital.com → React
hospital.com/api → Node backend
5️⃣ Free SSL (Must)
Use:
Let’s Encrypt (Certbot)
100% FREE SSL.
Security Best Practices (Very important for hospital)
✔ HTTPS mandatory
✔ Backend not publicly exposed
✔ MongoDB IP whitelisted
✔ Daily DB backup
✔ Strong passwords
✔ IAM limited access
This is enough for small hospitals.

MongoDB Atlas
❌ What NOT to use (costly)
❌ ECS Fargate
❌ EKS
❌ RDS (not for Mongo)
❌ Load balancer (₹1800/month alone)
❌ CloudFront initially
These double your bill.
易 Scaling Later (when hospital grows)
When users increase:
Upgrade EC2 → t3.small
MongoDB → M5
Add daily backups
Add second EC2 if needed
No re-architecture required.

✅ This is what real clinics use
Small & mid hospitals in India usually run on:
Single EC2
External DB
Simple architecture
Very low cost
